Online courses are a growing part of the community college experience, but many students, particularly minority students or students who are more at-risk, face challenges in passing those courses. This paper presents results from an experimental study of an effort to redesign a set of core introductory online courses to include a set of technology tools and instructional practices designed to improve students' experiences in the online environment. Results from the study showed that treatment students were less likely to withdraw, and minority students, specifically, were more likely to pass the class and to persist to the next year of college.

高科技，高接触度：在线课程干预对高等教育的学业成绩和持久性的影响

在线课程已成为社区大学体验中越来越多的一部分，但是许多学生，尤其是少数民族学生或高危学生在通过这些课程时面临挑战。本文介绍了一项旨在重新设计一系列核心在线入门课程的实验研究的结果，这些课程包括一组旨在改善学生在在线环境中的体验的技术工具和教学实践。该研究的结果表明，接受治疗的学生退学的可能性较小，特别是少数族裔的学生，更可能通过课程并坚持到下一年的大学学习。
